HERMES Data Model

hermes uses an internal data model to store the output of the different stages. All the data is collected in a directory called .hermes located in the root of the project directory.

You should not need to interact with this data directly. Instead, use hermes.model.context.HermesContext and respective subclasses to access the data in a consistent way.

Harvest Data

The data of the havesters is cached in the sub-directory .hermes/harvest. Each harvester has a separate cache file to allow parallel harvesting. The cache file is encoded in JSON and stored in .hermes/harvest/HARVESTER_NAME.json where HARVESTER_NAME corresponds to the entry point name.

hermes.model.context.HermesHarvestContext encapsulates these harvester caches.
